Submitted by: Edouard Bastarache (edouardb@sorel-tracy.qc.ca)
Ice Cream Flavor: Why change: vanilla
I decided to try it without lithium. My student women cannot
understand why I give them gloves or tell them to wash hands after
glazing! The result was interesting, much
different than the original. More matte much darker.You cannot always
avoid the lithium!
The next time I tried to adjust it in the studio, away from the
computer. I got very interesting glaze,you could not do it near the
computer, because you would see immediately the lack of alumina.This glaze
turned out like a ^6 barium or strontium turquoise matte.
I will try to adjust it.If I will not succeed I will use it as it
is,because I like the result. So thanks again for your part in
glazebase Eduard.
Before I adjusted, I tried it on two tera cotta tiles, looks even better.I
cannot explain why it works and not runny

I will upload the tera cotta tiles too, next to the white earthnware tile.
The Recipe is With my materials and with OUR oxides!
